The project:

The laboratory for Energy Intensified Reactor Engineering, together with several academic and industrial partners, performs an ongoing research in the framework of an ERC Synergy project SCOPE on application of novel structured catalysts in plasma flow reactors. This project aims at the design of a novel type of catalytic structured reactor plasma for (i) nitrogen fixation into ammonia or nitric oxides (NOx) and (ii) methane coupling into ethylene under non-thermal plasma conditions. Non-thermal plasma (NTP) is an ionized gas, created in mild conditions by applying electric energy to a gas, for example, a potential difference between two electrodes.

Studies on microelectrode design and micro-plasma are emerging. Spatially confining the plasma to dimensions of 1 mm or less is a promising approach to the generation and maintenance of stable, glow discharges at atmospheric-pressure. Micro-plasma arrays have already been described for applications in surface modification. Additive manufacturing (3D printing) technology provides a new way to manufacture objects with complicated structure and small dimension. In the case of catalyst preparation, a better control of catalyst structures and active component distribution can be achieved by using 3D printing.

The primary objective of this research is to determine the result of varying the heat and mass transport properties, which affect the design if the catalytic reactor operated under non-thermal plasma conditions. The temperature, concentration and velocity distribution will be obtained as a function of several design parameters (catalyst thermal conductivity, electric field strength, intrinsic reaction rate, etc.).

The catalytic reaction in the plasma reactors will be studied to determine the reactant conversion, product yields/selectivities and energy efficiency for the model reactions, for a wide range of reaction conditions (including gas flow rate, applied power, gas mixing ratio).
